NEC adopts Arm's Platform Security, develops facial recognition accelerator

NEC announced a strategic collaboration with Arm to drive the development of secure Internet of Things (IoT) solutions for Smart Cities using artificial intelligence (AI).

Under the alliance, NEC will adopt the Arm Platform Security Architecture, which is an industry framework for building securely connected devices. This framework includes the concept of threat modeling, architectural guidelines and implementation resources that reduce the cost, complexity, and risk associated with IoT security.

NEC is also developing a box-type accelerator device featuring real-time facial recognition that will be securely managed and provisioned by Arm Pelion Device Management. The accelerator will be equipped with the Arm Cortex-A53 processor. It will accelerate the device's facial recognition process and enable faster analytics by offloading the analytics workload carried out on servers or the cloud, thereby helping to reduce costs for networks and systems.

NEC says its facial recognition technology is the world's most accurate and fastest as measured by the U.S. National Institute of Standards and Technology (NIST) benchmark tests.

"We expect the new accelerator to promote further adoption of face recognition throughout many areas, including the public safety, entertainment and transportation fields, as it contributes to the security and convenience of consumers worldwide," said Naoki Hashitani, SVP, NEC Corporation.

NEC adds 5G Traffic Management

NEC launched an enhanced Traffic Management Solution (TMS) for 5G that improves the throughput of high-speed networks that support data transfer rates of more than 5 Gbps. 

NEC said 5G requires greater throughput from core networks through the wireless access networks. However, there will be a mixture of networks with different communication speeds, such as 4G and 5G, and, therefore, it is necessary to assure network stability at the time of a terminal's handover between different types of networks.

NEC's enhanced TMS features advanced component software that increases the performance and accuracy of analytics. Moreover, Dynamic TCP Optimization, a function that enables control in response to changing network conditions, has extended its scope to the ultrahigh-speed range of 5Gbps or more.

The company claims its enhanced TMS in a 5G test environment has improved 5G communications quality by increasing throughput by approximately 24% in the ultrahigh-speed range of 5Gbps or more; reducing download time during the handover from 4G to 5G by approximately 27%; and reducing the time to reach the maximum speed during the handover from 4G to 5G by approximately 64%.

"NEC contributes to a better experience for end users and more efficient network operations for CSPs by continuing to enhance TMS," said Kazuhiro Tagawa, General Manager, Network Solutions Division, NEC Corporation. "Our TMS has been adopted by over 20 CSPs worldwide and we look forward to seeing it drive the further advancement of 5G."

NEC and Google test subsea modulation using probabilistic shaping

NEC and Google have tested probabilistic shaping techniques to adjust the modulation of optical transmission across the 11,000-km FASTER subsea cable linking the U.S. and Japan.

The companies have demonstrated that the FASTER open subsea cable can be upgraded to a spectral efficiency of 6 bits per second per hertz (b/s/Hz) in an 11,000km segment -- representing a capacity of more than 26 Tbps in the C-band, which is over 2.5X the capacity originally planned for the cable, for no additional wet plant capital expenditure. The achievement represents a spectral efficiency-distance product record of 66,102 b/s/Hz.

The field trial was performed with live traffic on neighboring channels.

The companies said their test used near-Shannon probabilistic-shaping at a modulation of 64QAM, and for the first time on a live cable, artificial intelligence (AI) was used to analyze data for the purpose of nonlinearity compensation (NLC). NEC developed an NLC algorithm based on data-driven deep neural networks (DNN) to accurately and efficiently estimate the signal nonlinearity.

"Other approaches to NLC have attempted to solve the nonlinear Schrodinger equation, which requires the use of very complex algorithms," said NEC's Mr. Toru Kawauchi, General Manager, Submarine Network Division. "This approach sets aside those deterministic models of nonlinear propagation, in favor of a low-complexity black-box model of the fiber, generated by machine learning algorithms. The results demonstrate both an improvement in transmission performance and a reduction in implementation complexity. Furthermore, since the black-box model is built up from live transmission data, it does not require advance knowledge of the cable parameters. This allows the model to be used on any cable without prior modeling or characterization, which shows the potential application of AI technology to open subsea cable systems, on which terminal equipment from multiple vendors may be readily installed."

Transpacific FASTER Cable Enters Service with 60 Tbps Capacity

The world's highest capacity undersea cable system has entered commercial service -- six fiber pairs capable of delivering 60 Terabits per second (Tbps) of bandwidth across the Pacific.

FASTER is a 9,000km trans-Pacific cable connecting Oregon and two landing sites in Japan (Chiba and Mie prefectures). The system has extended connections to major hubs on the West Coast of the U.S. covering Los Angeles, the San Francisco Bay Area, Portland and Seattle. The design features extremely low-loss fiber, without a dispersion compensation section, and the latest digital signal processing technology.

Google will have sole access to a dedicated fiber pair. This enables Google to carry 10 Tbps of traffic (100 wavelengths at 100 Gbps). In addition to greater capacity, the FASTER Cable System brings much needed diversity to East Asia, writes Alan Chin-Lun Cheung, Google Submarine Networking Infrastructure.

Construction of the system was announced in August 2014 by the FASTER consortium, consisting of China Mobile International, China Telecom Global, Global Transit, Google, KDDI and Singtel.

DOCOMO, and is now being utilized as a base station control unit.

"DOCOMO aims to deploy and expand our commercial 5G services efficiently by maximizing the use of existing communications equipment," said, Hiroshi Nakamura, Executive Vice President, Chief Technology Officer and Member of the Board of Directors, NTT DOCOMO. " This agreement with NEC is in line with that policy and we expect it to make a significant contribution to our 5G services. Going forward, DOCOMO accelerates co-creation of new services and businesses with vertical industry partners."

NTT Docomo and NEC test 5G to race car traveling at 300 km/h

NTT DOCOMO and NEC conducted a test of 5G connectivity to a race car moving at 305 km/h (190 mph)

The test, which used 28 GHz spectrum, sustained a downlink of 1.1 Gbps between the 5G base station and the 5G modem in the car moving at 293 km/h and a fast handover during communication between 5G base stations and a 5G mobile station moving at 290 km/h. In addition, the trial succeeded in a wireless live relay of 4K high-frame-rate video via uplink from a 5G mobile station moving at 200 km/h. Both the 5G base station and 5G mobile station in the car were equipped for beamforming, which concentrated radio power in a specific direction, and beam tracking, which switched the direction of the beams to follow the 5G mobile station as it moved at high speed.

The trials were conducted last month at the Japan Automobile Research Institute (JARI).

The 4K video transmission operated at 120-frames-per-second and used NTT's real-time 4K high-frame-rate HEVC codec.

Other companies involved in the trials included DOCOMO 5G Open Partner Program participants, Sony Business Solutions Corporation, and DOCOMO TEAM DANDELION RACING manager Dandelion Limited.

NEC develops digital beamforming for 5G in 28GHZ band

NEC has successfully tested a new digital beamforming transmission method that uses a massive-element active antenna base station and 28 GHz band spectrum.

The demo is described as the simultaneous beamforming transmission (four multi-user MIMO) from a single massive-element active antenna system (AAS) to four terminals.  NEC achieved a 3.1 Gbps cell throughput by applying a frequency bandwidth of 300 MHz.
 
NEC said its massive-element AAS, supporting a 28 GHz band, adopts a fully digital control system, which improves the precision of beamforming. The fully digital control system enables simultaneous beamforming in multiple directions from a single massive-element AAS unit and efficiently implements high-speed and high-capacity communication without interfering with adjacent users through spatial multiplexing.

The beamforming takes into account multipath, a non-direct wave signal, and moderately adjusts beam directions as needed. It also cancels out interference through multipath and reduces performance deterioration caused by inter-cell interference.

NEC enables its advanced beamforming without digital/analog signal and frequency converters. Instead, the massive-element AAS adopts a fully digital control system with less power and more compact conversion functions.

"In order to effectively implement sophisticated services that apply 5G features from 2020 onward, it is essential to utilize 28 GHz and other high frequency radio bands, which enable the securing of wide bandwidth, and the utilization of beamforming," said Katsumi Tanoue, Deputy General Manager, Wireless Access Solution Division, NEC Corporation. "Moving forward, NEC will continue its efforts in development and demonstration tests for a massive-element active antenna base station system that delivers high speed, high capacity and massive connectivity."

NTT demos 118 Tbit/s transmission on multi-core fibre

NTT, together with six partners, KDDI Research, Sumitomo Electric Industries, Fujikura, Furukawa Electric, NEC and Chiba Institute of Technology (CIT), announced a demonstration of what is claimed as the highest transmission capacity of 118.5 Tbit/s using a multi-core fibre with four optical paths within the same diameter as currently used fibre.

NTT noted that a conventional glass diameter of 125 µm in accordance with the international standard enables the use of existing fibre fabrication and optical connector technologies. The demonstration is designed to validate the concept of multi-core fibre-based long-haul and high capacity transmission system comprising multiple vendor technologies and advance the application of multi-core fibre technology.

In the new fibre, 4-5 cores can be arranged within a 125 µm diameter while maintaining the same transmission quality as current optical fibre, with a 316 km multi-core transmission line realised with a 0.21 dB/km average loss, concatenating standard diameter multi-core fibre with 4 cores fabricated by multiple vendors.

As part of the new design, Sumitomo Electric, Fujikura and Furukawa each fabricated a multi-core fibre with 4 cores and more than 100 km length. All multi-core fibres can be used in the 1260 to 1625 nm wavelength region and provide similar transmission properties to current SMF with mode filed diameter at 1550 nm of 9-10 µm).

The fabricated multi-core fibres were divided into a 20-40 km sections and three transmission spans with a length of 104-107 km were re-constructed by splicing the multi-core fibres provided by different vendors. A satisfactory low loss comparable to conventional SMF was achieved, with average loss of four cores in each span 0.22 dB/km or less, including splicing losses.

In addition, three multi-core optical amplifiers fabricated by NEC, KDDI Research, NTT and Furukawa were inserted at each end of three spans to compensate the signal attenuation. Cladding pumping type multi-core optical amplifiers designed to reduce power consumption were used, enabling a 16% improvement in power usage.

To confirm the performance of the constructed multi-core transmission line to beyond 100 Tbit/s transmission, 16QAM-based 116-wavelength signals were prepared and the output signal quality over 316 km transmission was examined.

Additionally, Fan-In/Fan-Out devices developed by NTT and Furukawa were used to input/output signals to and from each core of the multi-core fibre. Pluggable optical connectors with existing MU-type or SC-type interfaces from CIT and NTT were used to connect the input/output end of the multi-core transmission lines and Fan-In/Fan-Out devices.

The work was partially based on work commissioned by the National Institute of Information and Communications Technology (NICT), and the companies stated that they aim to introduce the standard diameter multi-core fibre by the early 2020s. The achievement was reported in early August as a post deadline paper at the Opto Electronics and Communications Conference (OECC 2017) in Singapore.
